Description

Technical Field

[0001] The utility model relates to the technical field of vertical oil pumping units, in particular to a vertical oil pumping unit rope hanger. Background Art

[0002] The oil pump uses a rope hanger to adjust the relative position between the rope hanger and the steel cable. For example, in a rope hanger for an oil pump disclosed in Chinese patent literature (patent number: CN201821535836.1), the relative position between the rope hanger and the steel wire rope is adjusted by rotating the adjusting bolt to push the adjusting block downward and drive the adjusting column to move. The adjusting block is only provided with an adjusting bolt at one end, resulting in only one end of the adjusting block being subjected to force during the process of the adjusting bolt pushing the adjusting block. The uneven force of the adjusting block causes the adjusting column to slightly deviate when moving downward, resulting in an increase in the friction between the adjusting column and the housing, which affects the adjustment of the relative position between the rope hanger and the steel wire rope. In addition, the adjusting bolt is not provided with any fixing structure. The force between the steel wire rope and the adjusting column is applied to the adjusting bolt through the adjusting block, which may cause the adjusting bolt to reverse, making the relative position adjustment between the rope hanger and the steel wire rope invalid.

[0003] Therefore, we propose a vertical pumping unit rope hanger. Utility Model Content
